LUBRICA'IING APPARATUS.

Application filed m 17,

This invention aims to improve lubricating apparatus of the class in which a. manually operable, portable tiller is employed to till and to replenish froi'n time to time receptacles such as oil cups and oil holes used for motorcar chassis lubrication, and for the lubrica tion oat other machinery of various kinds.

'ihe invention will be best understood by reference to the following description, when taken in connection with the accompanying drawings of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

in the drawings: i

Fi 2 is a plan of a portion of the apparatus illustrated in Fig. 1, onan enlarged scale;

Fig. 3 is a sectional view on line 33 of Fig. 2; and

Fig. 4t is a sectional view on an enlarged scale on line iti of Fig. 1.

Referring to the drawings, and to the embodiment of the invention which is selected :l'or er-templification, there is shown in Fig. 1 a lubricating apparatus comprising a filler and a irceiver, the filler comprising a reservoir having an outlet conduit leading therefrom, herein exen'iplitiod byan oil can presenting a reservoir 53 and a spout 6. The receiver 1s eX- cinpli tied by an oil cup presenting a reservoir 7, having an inlet 8 and an outlet 9, the former being normally closed by an appropnate closure, herein a cover 10, which is spring controlled, the cover to that end being secured to a stem 1.1, which is encircled by a helically coiled compression spring 12, the upper end of which is seated against an appropriate ill- 6d abutment, herein a yoke 13, which spans the inlet, but leaves space for the introduction cit lubricant, while the other end of the spring rests against a movable abutment 14 carried by the stem. In the present embodiment, the stem also carries a permeable valve 15 of felt or other appropriate material, which in its normal position is seated against atapered valve seat 16'between the inlet and outlet, the arrangement being such that when the oil cup and the connections leading to the bearing have been flooded with oil, and the cover and valve closed, the oil remaining in the reservoir gradually seeps through the permeable valve and continues to supply oil in small quantities to the bearing, in the intervals between replenishing operations. 1 The cover and body of the oil cup present abutments 17 and 18 for 1924; Serial No. 726,517.

cooperation with the cover opening and receptaole filling implements now to be described in detail.

Suitably carried by the filler is. an orificepositioning closure opener, which lifts the cover and opens the valve, positioning an out let orifice 19 ot' the spout 6 for delivery of oil into the oil cup. In the present embodiment, this orifice-positioning closure opener comprises a fork presenting two arms 20 (see Fig. 2), adapted to enter the spaces presentedby the abutments 17 and 18 at opposite sides of the oil cup, and to embrace the latter, thereby to position the outlet orifice of the spout laterally with relation to the oil cup. By this means, the outlet orifice is positioned horizontally in a direction transversely of the oil cup, and also vertically with respect to the oil cup, the vertical positioning being due to the fact that the spring-pressed cover urges the arms in a downward direction onto the abutment 18 presented by the oil cup. The advance or the filler is limited in a most convenient manner by an abutment 21 presented by the fork, and which brings up againstthe side of the reservoir, as best shown in Fig. 2.

To facilitate the entrance of the arms of the fork into the spaces presented between the fixed and movable abutments provided on the oil cup, the arms inthe present example present wedge-like or tapered tormat-ions22 (see Fig. 1'), as viewed in profile, while, as viewed in plan, their extremities herein diverge somewhat, as at 23 (see Fig. 2). V7 hen, therefore, the fork is applied to the cup and, thrust forward, the cover is easily lifted, tilted, and pushed somewhat to one side, at the same time lifting the valve. During this movement, the forward end of the spout enters the space between the cover and inlet of the reservoir, and the outlet orifice of the spout is presented in a position directly above and nearly central with respect to the inlet (see Fig. 3). WV hen the parts are in this position, pressure on the bottom of the oil can expels oil from the reservoir through the spout into the oil cup, after which the cover is allowed to close by simply withdrawing the oil can in a rearward direction, the spring asserting itself to restore the cover and the valve totheir normal closed position.

It happens that there are many places about motor cars and other machinery which it is not customary to equip with oil cups. Some of these parts have-common oil holes, while others have none at all, and in the latter case,it is usual to apply thetip of the oil can spout at a point where the oil, when expelled, will run between the bearing surfaces. In situations such as these, it .isnot desirable to use the coverope ner, and in fact, inmost cases it is desirable and man r'times altogether necessary, to have the cover openerout of the way, so that the forward end-of the spout" will be entirely unobstructed. To

these ends, therefore, the cover opener is I mountedfor movement into a retracted posi tion, by means such as'those that are now to.

be described. In the present embodiment, the coverf'openeris conveniently advanced and retracted by being pivotally mounted on the oil can spou't,--so that it may be swung from lines;

its normal position shown infull lines in Fig. 1 to thefretracted position shown in dotted IIerein, the cover plates'24,conveniently secured together as by'fa rivet 25 extending therethrough, and these plates are formed to presenta'second fork, herein comprising two arms 26 (see Fig; 2), which embrace a part of the filler, herein a clamping collar 27 disposed about th'e spoutlsee'Fig. 4:)- Qwing to the usual tapered formation orthe spout, ordinary methods of securing the collar to the spout would be unsatisfactory, and I have therefore provided anespecially practicable and effective means of attachment, which. will now behdescribe d.

To provide a positive interlocking c'onnection' between the collar and the: spout,

the latter herein is provided withan indentation 28, conveniently made by squeezing the wall 1n an inward'direct on, and this indentation receives aclamping bolt 29, whichnot only interlocks with the spout, but serves to urge the sides of the clamping collar to,-

ward the spout and to squeeze the latter there between, the bolt to that end having at one enda head 3Q which rests against one side of I the collar, and at its other end a nut 31,which rests'against the opposite. side 01: the collar (see Fig. {The clamping collar herein is generally ll-shaped, and has arms which embrace the oil can spout, the terminal portions of' these-"arms being curved inwardly as M33, and partially wrapped about the spout.

, A s the spout has a tapered formation, the

arms of 'theclamping collar are correspondingly tapered (see 2) that is to'say, the surfaces'which engage the spout are not cylindrical,but are of conical form corresponding tr), the conicalformation ofthe spout. /Vhen these surfaces are forced toward each other by the action of the clamping bolt, the1resultant forces on the wall of the spout are in the general directions of thearrowsA in Fig.4, and the spout is therebycrowded againstthebolt; that is tosay," the bolt is thereby seated all the more firmly in the in dentation in the spout.

opener comprises two- The head and nut of the bolt present convenient trunnions for the arms 26,fthe nut to that end in the present example being cylindricalaround its periphery, and to enable the nut to be turned whenassembling the parts,

the nut herein is provided with a slot 34 to receive a special screw-driver which is bifurcated to span the threaded end of the bolt.

When the nut'has been screwed firmly' into place, it is convenientlyprevented from turning by heading,or'staking the end of the bolt as at 35, thus forcing some of the material of the bolt into the slot in the nut.

To hold the cover opener against accidental swinging movement on the trunnion's, I have provided spring friction means conveniently presented by the arms 26 themselves, which.

cover opener in its advanced position, I prefer to provide locking means definitely to retain the opener in such position in the manner now to be described.

Still referring to- Fig. 4, one ofthe arms 26 herein is provided with a shallow depres sion 36 adapted'to receive a protuberance,

such as a steel ball13'Z mounted on theside of .one of the arms 32 of the clamping collar, as

by providing the latter arm with a seat 38 of conical formation to receive the ball. By reference to the left handfside of Fig. 4, it will 1 be observedthat this arm 26 is separated from the correspondingportion 32 by a space sufficien-t to utilize the spring pressure afforded by the 'arm26 to urge the ball into the depression when in registration therewith, while permitting the ball to ride out of the depression when suflicient force is applied to thecover opener. When the ball is not in registration with the depression, the ball simply rides along thefiat surfaceof the adjacent face of the arm. Thus I haveprovided means automatically to posit on the cover opener definitely in its advanced working position, and'to" hold the same frictionally against accidental movement when moved from itsnorn' ia'l position. This can be accomplished instantly and conveniently, without the use of tools and without loose parts, which might be'dropped or lost} Having thus described one embodiment of the invention,=but without limiting myself thereto, what I claim A and desire by Letters Patent to secure 1s: a
